L. MILLER. Bale Ejector for Presses.

Patentedlani UNITED STATES PATENT OFFICE.

LE WIS MILLER, F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO JOHN P. VERREE, TRUSTEE, OF SAME PLACE.

BAL.E-EJ ECTOR FOR PRESSES.

SPECIFICATION forming part of Letters Patent No. 236,609, dated January 11, 1881.

Application filed October 23, 1880. (No model.)

To all whom it may concern Be it known that I, LEWIS MILLER, of Philadelphia, in the county of Philadelphia, and in the State of Pennsylvania, have invented cer- Iain new and useful Improvements in Bale- Ejeetors for Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain improvements in mechanism for ejecting the bales from cotton and other'bale presses after being suitably compressed and bound therein; and

it has for its object to dispense with the necessity of obstructing the spaces between the channel-bars with the ejecting mechanism, as in the machines heretofore constructed, and

thus leave such spaces free for the application of the binding-bands around the bale; and, further, to provide for ejecting the bale with rapidity and surety at any desired time, as more fully hereinafter specified. These 0b- 2 5 jects I attain by the apparatus and mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of my invention as applied to a cotton-press; Fig. 2,

0 a longitudinal vertical section, showing the lower portion of a cotton-bale press with my invention applied; and Fig. 3 represents a sectional view, showing a portion of the apparatus for actuating the bale-ejecting mechanism in detail.

The letter A indicates the lower platen of a cotton-bale press, provided with the usual channel-bars B. Two ormore of the channel-bars, B, instead of being permanently fixed to the bed of the platen of the presses, as ordinarily constructed, are detached from the bed and made somewhat longer than the others, so as to project at each side, as indicated. At one side of the platen they are pivoted or ful- 5 crumed to suitable standards 0 provided for the purpose, and at their other ends are conneeted by means of a longitudinal connectingbar, D.

The letter E indicates asteam or air cylinder,

having a piston, F, and piston-rod G extending through the upper head. The said cylinder is firmly secured to the lower platen by means of bolts at an angle thereto, as shown. The upper end of the piston-rod connects with a crosshead, H, from the ends ofwhich extend the con- 5 5 necting-rods I, which are pivoted to slides working in ways K at opposite sides of the cylinder. The said slides have pivoted to them, also, the pitmen L, which connect with the bar D in such manner that when the pis- 6o ton-rod is projected upward it will elevate the movable channel-bars at an angle, as indicated in the drawings, so as to eject or throw off the bale at the opposite side of the press.

As the ejecting mechanism requires to be operated with considerable rapidity, it is found advantageous to cushion the piston at the ends of its stroke; and to provide for lifting the piston at the beginning of its upward stroke when thus cushioned, a small pipe, M, with suitable cock N, is carried from the steam-pipe P, which admits steam to the lower part of the cylinder. By this means steam may be supplied to the cushion-chamber at the lower end of the cylinder, to elevate it past the end of the pipe P, by which the steam, in proper quantity, is supplied to complete the stroke with the proper rapidity.

The steam supplied to the cylinder may be regulated by means of suitable cocks or mechanism under control of an operator or attendant.

Instead of steam, it is evident that compressed air or other similar expansible fluid may be employed for operating the apparatus, if desired, without departing from my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is 0 The combination, in a cotton-bale press, with the platen thereof, of movable channelbars fulcrumed to said platen and suitable operatin g mechanism, whereby said bars may be elevated and serve as ejecting levers or bars, substantially as specified. I

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of October, 1880.

LE WIS MILLER.
